Add yapf configuration file

Some of the default behaviors of yapf do not match the styling
preferences of Airship and OpenDev, such as line breaks between
dictionary key/value pairs. This change sets the style template for yapf
(PEP-8) and sets a few knobs to help remedy problematic behavior.

Adds .style.yapf configuration file.

Updates styling of existing files using new configuration.
